항공기 산업은 가장 첨단 산업으로 평가됩니다., 그리고 항공기 부분에 대한 요구사항이 매우 엄격합니다.. 그만큼 7075 그리고 7005 항공기용 알루미늄 시트에 가장 일반적으로 사용되는 알루미늄 합금입니다.. 오늘 우리의 주제는 7075 알루미늄 시트,

7075 아연을 주성분으로 하는 알루미늄 합금이다., 그러나 때로는 소량의 마그네슘과 구리가 첨가되기도 합니다.. 그 중, super-hard aluminum alloy contains lead, 아연, magnesium and copper alloy, the hardness is close to the steel and can be heat treatment. 7075 aluminium sheet is a high-strength heat-treatable alloy with good corrosion resistance and good mechanical properties.As a typical aircraft aluminium sheet, 7075 aluminum sheet is a cold-treated forging alloy with high strength and high hardness, far better than mild steel.

7075 aluminum sheet plate is one of the most powerful commercial alloys, with common corrosion resistance, good mechanical properties and anode reaction. The fine grain makes the deep drilling performance better, the tool wear resistance is enhanced, the thread rolling is different from the weight, and the preferred metal material with lower density requirements and higher hardness requirements.

7075 aluminum plate is usually used to manufacture aircraft structures and other high-stress structural parts that require high strength and high corrosion resistance, such as aircraft upper and lower wing panels, purlins and partitions on aircraft.

The aluminium sheets for aircraft 7075 has good solution after solution treatment, good heat treatment strengthening effect, high strength below 150 ℃, good low temperature strength, poor welding performance, stress corrosion cracking tendency, double-stage aging can improve anti-SCC performance.
